Definitions
- the present invention relates to a device for fastening a bearing ring in a housing or onto a shaft.
- a device for fastening a rolling-contact bearing ring in a housing is disclosed in DE-C 667 422.
- the fastening is done with the aid of two bushes.
- the bushes When the bushes are mounted, they are pushed onto a double-wedge ring and are pressed into a groove in the housing.
- this known device has several disadvantages. First, it is comprised of a relatively large number of parts, which makes its assembly difficult. Secondly, it is impossible to achieve good seating, since bushes, which are subject to tolerances, are arranged between the bearing ring and the housing. In particular, no reliable axial fastening is expected, specifically because the bushes may easily loosen over time, for example as a result of shocks, and the peened-over edges may be bent back.
- a groove is formed in the cooperating periphery of either the rolling contact bearing ring or of the housing or shaft.
- the groove comprises a first groove that extends axially from the lateral entrance side and a second groove that extends axially in from the first groove and is both axially and radially inclined forming a conical surface at the periphery of the rolling contact bearing ring.
- An intermediate ring is installed from the entrance side of the bearing in the first groove and is plastically deformed conically to extend into the second groove.
- the recess in the bearing ring or in the housing or shaft receives the deformed part of the intermediate ring.
- the remaining diameter of the periphery of the rolling contact bearing ring at and on the cooperating periphery of the housing or shaft are of the same diameter so that the peripheries rest against each other.
- the intermediate ring may include a flange that engages the lateral entrance side of the first groove and positions the intermediate ring.
- the intermediate ring may be the peripheral region of a pot-shaped cover over the entrance side of the bearing at the entrance to the first groove.
- the bearing ring may be installed in the housing or shaft with one ram and the intermediate ring may thereafter be installed from the entrance side into the first groove and plastically deformed into the second groove by a second ram. This fastens both the bearing ring and the intermediate ring in place.
- connection is achieved in particular by the remaining diameter axial regions of the bearing ring corresponding to that of the housing or of the shaft. If the contact-bearing running ring were to try to move out axially, the plastically deformed part of the intermediate ring would have to be sheared off. However, this would require axial thrust forces at a level which does not occur in operation.
- the radially overlying groove and cooperating recess that receive the intermediate ring are bounded by opposite radially spaced apart surfaces, one on the bearing ring and the other on the housing or shaft.
- the surface on the bearing ring has a greater angle from the axis than the other surface providing better adhesion of the intermediate ring in the recess.
- a flange on one end of the intermediate ring limits the push-in depth or axial depth of that ring.
- Mounting of the bearing rings is particularly beneficial using a special procedure. Specifically, if the pressure on the first ram which presses in the bearing in the housing or on the shaft is maintained until the intermediate ring is pressed in by the second ram, the contact bearing running ring springs back axially after the removal of the second ram. This produces additional clamping in the shearing cross section of the intermediate ring.
- the invention also includes the geometric converse of the specifically disclosed arrangement, wherein the intermediate ring is seated in the housing or on the shaft and the recess is arranged in the running ring.
- FIG. 1 shows a longitudinal section of a fragment of a ball bearing with an intermediate ring according to the invention in the preassembled state
- FIG. 2 shows a smaller fragment according to FIG. 1 in the assembled state
- FIG. 3 shows a fragment of one variant of FIG. 2
- FIG. 4 shows a cross section through a further variant of FIG. 2;
- FIG. 5 shows a longitudinal section of an alternate embodiment of the ball bearing with an intermediate ring.
- FIG. 1 shows a fragment of an outer ring 1 of a ball bearing 2 before the bearing is fully assembled.
- a first groove 3 extends axially in from the lateral entrance side of the bearing.
- the first groove 3 merges into an axially adjacent second conical section groove 4 which is inclined radially outwardly. Both grooves are provided on the outer peripheral surface of the outer contact bearing ring.
- An intermediate ring 5, which is initially not radially deformed, is arranged in the groove 3 and is cooperatingly oriented axially.
- the groove 3 is open to the axial side of the bearing to receive the intermediate ring.
- this structural unit including the intermediate ring on the bearing outer ring 1 is then pressed into a housing 6 that surrounds the outer ring, this produces the combination shown in FIG. 2.
- An axially inward part 5' of the intermediate ring 5 is pushed onto the conically outwardly inclined axially adjacent conical section 4 of the groove of the outer ring 1.
- This first conical section has an angle of about 25° to the axis
- the part 5' is plastically deformed in the groove as a result.
- That part 5' is then pressed into a cooperatingly shaped recess 7 in the housing 6.
- This recess 7 also has a radially inwardly facing conical section 6', on which the ring part 5' comes to rest.
- This second conical section has an angle of about 20° to the axis.
- the remaining diameter region 8 of the external periphery of the outer ring 1 located axially inward past the grooves 3, 4 and the recess 7 corresponds in outer diameter 9 to the inner diameter of the inner periphery of the housing 6.
- the bearing outer ring 1 If the bearing outer ring 1 then tries to move axially outward from the housing 6, the ring 1 is prevented from so moving by a positive connection.
- the part 5' which has been plastically deformed and therefore projects into the recess 7, is the significant element. Axial movement could occur only if the axial forces are extremely large. However, a shearing action on the part 5 in the region 10 would be necessary. Such high forces are not expected in practice, since other parts of the bearing would already have been destroyed.
- FIGS. 3 and 4 show that the intermediate ring 5 is able to perform further functions.
- the ring 5 has a radially oriented flange 11 in the region of the axial entrance end face of the outer ring 1. This defines the insertion depth of the intermediate ring using simple means.
- FIG. 4 shows a pot-shaped cover 12 which has the intermediate ring defined as and around its periphery and which is optimally fastened in the axially oriented region 12', as described above.
- the cover 12 both seals the bearing and defines the intermediate ring.
- the intermediate ring is seated in a groove on the running ring of the bearing while the housing around that ring has the recess.
- the recess is in the bearing running ring while the intermediate ring is simply seated on the housing.
- FIG. 5 illustrates an alternate embodiment wherein the intermediate ring is between the bearing inner ring and the shaft. Elements in FIG. 5 which correspond to those in FIGS. 1-4 have the same reference numbers and are not described in detail.
- the inner ring 15 of the ball bearing 2 is shown mounted on the shaft 18 with which it rotates.
- the axially extending first groove 23 merges into an axially adjacent second conical section groove 24 which is inclined radially inwardly.
- Both of the grooves 23 and 24 are provided on the outer peripheral surface 33 of the inner contact bearing ring 15.
- An intermediate ring 25 has the characteristics of the above-described ring 5 and is installed in the groove 23 and the adjacent conical section 24, as was done with the first embodiment.
- the intermediate ring 25 has an axially inward part 25' which is pushed onto the conically inwardly inclined, axially adjacent conical section 24 of the groove 23 in the inner ring. That part 25' is then pressed into a cooperatingly shaped recess 27 in the shaft 18.
- This recess 27 also has a radially inwardly facing conical section 26' on which the intermediate ring part 25' comes to rest.
